The silver in a piece of jewelry has a volume of 0.25cm^3. If the density of silver is 10.5g/cm^3, what is the mass (in grams) of the silver in the piece of
jewelry?

The answer is

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume of silver = 0.25 cm³

density = 10.5 g/cm³

The mass is

mass = 10.5 × 0.25 = 2.625

We have the final answer as

Hope this helps you

58750.08068 is the answer i think

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
