## How do you answer density Questions?

Tips for Answering Density Questions When you’re asked to calculate density, make sure your final answer is given in units of mass (such as grams, ounces, pounds, kilograms) per volume (cubic centimeters, liters, gallons, milliliters). You may be asked to give an answer in different units than you’re given.

**How do you solve for density?**

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).

**What is the density of 15.0 mL and 40.5 g?**

2.70 g/mL

You are asked to calculate density. Hence, you take the formula for density, which is d = m / V. Then, you plug into the formula the values of mass and volume and calculate. d = 40.5 g / 15.0 mL = 2.70 g/mL A zero after 2.7 is added as you need 3 significant figures.

### How do you find density with grams and ML?

Calculate the density of an object that has a mass of 25.0g and the volume is 10.5ml. Calculate the mass of an object that has a density of 8.92 g/ml and the volume is 5.25 ml….

vol= | 21.0g |
---|---|

12.0g/ml |

**How do you find volume using density?**

Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters.

**How do you find density without mass?**

A simple method based on the moment of forces and Archimedes’ principle is described for finding density without measuring the mass and volume of an object. The method involves balancing two unknown objects of masses M1 and M2 on each side of a pivot on a metre rule and measuring their corresponding moment arms.

#### What is the volume of a block that is 8.4 cm by 5.5 cm by 4.6 cm?

212.52 cubic cm

Length of the copper box= 8.4 cm. Breath of the copper box = 5.5 cm. Height of the copper box= 4.6 cm. = 212.52 cubic cm.

**What is the volume of 35.5 g of ethyl alcohol?**

Therefore, the volume is 45. 0mL.
