Question

What is the mass of 5.00 moles of K2SO4

Answer 1

Answer:

mass= molar mass*number of moles

So,

5*174=870 grams of $K_{2} SO_{4}$

Explanation:

Answer 2

Given: The given quantity is 5 moles $K_2SO_4$.

To find: We have to find the mass.

Solution:

To determine the mass of 5 moles of $K_2SO_4$ we have to follow the below steps-

The atomic mass of K is 39.

The atomic mass of Sulfur is 32 and the atomic mass of Oxygen is 16.

The compound has two potassium atoms, one sulfur atom and four oxygen atoms.

So, its mass will be-

$39 \times 2 + 32 + 16 \times 4 \\ 78 + 32 + 64 \\ = 174$

One mole of $K_2SO_4$ has mass 174.

5 moles of $K_2SO_4$ will have

$174 \times 5 = 870$

The mass of 5 moles of $K_2SO_4$ is 870 gram/mole.
