What is the mass of an object with a density of 5 g ml and a volume of 15 ml?
Answer: The mass of the object is 45 g.
How do you find mass with density and ML?
- mass = volume x density.
- mass = 30 ml x 0.790 g/ml.
- mass = 23.7 g.
How do you find the mass of an object with density and volume?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
How do you find the mass of an object with density?
Next, look up the density of gold, which is 19,320 kg/m3. To convert to grams per liter, you simply need to multiply by 1, so the density is 19,320 g/l. Now you can calculate the mass from the density using the formula m = ∂V and obtain the answer in grams.
What is the formula mass?
One can consider the mass of an object as a measure of how much physical “stuff” makes up that object. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume….
What is the formula of mass and weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms….
What is the time formula?
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
How do you calculate minutes?
First, divide the number of seconds by 60 to get it into minutes form. Add this to your number of minutes, then divide again by 60 to get hours.
How do you calculate difference in time?
- Convert both times to 24 hour format, adding 12 to any pm hours. 8:55am becomes 8:55 hours (start time)
- If the start minutes are greater than the end minutes…
- Subtract end time minutes from start time minutes…
- Subtract the hours…
- Put(not add) the hours and minutes together – 6:45 (6 hours and 45 minutes)
What is the formula of rate?
However, it’s easier to use a handy formula: rate equals distance divided by time: r = d/t.
What is the formula of principal?
Principal Amount Formulas We can rearrange the interest formula, I = PRT to calculate the principal amount. The new, rearranged formula would be P = I / (RT), which is principal amount equals interest divided by interest rate times the amount of time….
What is the formula for calculating principal?
The formula for calculating Principal amount would be P = I / (RT) where Interest is Interest Amount, R is Rate of Interest and T is Time Period.
What is the rate in math?
A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
What are 3 examples of rates?
Some examples of rate include cost rates, (for example potatoes cost R16,95 per kg or 16,95 R/kg) and speed (for example, a car travels at 60 km/h). When we calculate rate, we divide by the second value, so we are finding the amount per one unit.
What is price per unit?
The unit price of an item is the cost per unit of the item. We divide the price of certain number of units of an item by the number of units to find the unit price of that item. The item with the smaller unit price is considered as the “better buy”.
What is the difference between a rate and a unit rate?

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
What is rate and ratio?
A ratio is a comparison of two numbers. A rate , by contrast, is a comparison of two quantities which can have different units. For example 5 miles per 3 hours is a rate, as is 34 dollars per square foot.
What is a unit rate example?
