2.87mL of 2.5 M K2SO4 are required to obtain 1.25 grams of the compound.

<h3>HOW TO CALCULATE VOLUME?</h3>

The volume of a substance can be calculated by dividing the number of moles of the substance by its molarity. That is;

volume = no. of moles ÷ molarity

According to this question, 2.5M K2SO4 are required to obtain 1.25 grams of the compound. The volume can be calculated as follows:

Molar mass of K2SO4 = 174.26 g/mol

moles of K2SO4 = 1.25g ÷ 174.26g/mol

moles of K2SO4 = 0.00717moles

Volume = 0.00717moles ÷ 2.5

Volume = 0.00287 L = 2.87mL.

Therefore, 2.87mL of 2.5 M K2SO4 are required to obtain 1.25 grams of the compound.

If you have a density of 100 kg/L and a mass of 1000 g what is the volume (please explain)
olchik [2.2K]

Answer:  Volume =  0.01L

Explanation:

The density of a substance is given by; Density =  Mass / Volume.

In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L

For the units to be uniform, we convert 1000g to Kg = 1Kg

Therefore, Volume = Mass / Density =  1Kg / 100Kg/L = 0.01L
