Calculate the molar mass for sodium sulfate, n a2so4. a sample of sodium sulfate with a mass of 300.0 g represents what number of moles of sodium sulfate?

300 grams of sodium sulfate represents 2.112 moles

Explanation:

Step 1: Data given

Mass of Na2SO4 = 300.0 grams

Step 2: Calculate the molar mass of Na2SO4

Na = 22.99 g/mol

S = 32.065 g/mol

O = 16 g/mol

Molar mass of Na2SO4 = 2*22.99 + 32.065 + 4*16

Molar mass of Na2SO4 = 142.045

Step 3: Calculate moles of Na2SO4

Moles Na2SO4 = mass Na2SO4 / molar mass Na2SO4

Moles Na2SO4 = 300.0 grams / 142.045 g/mol

Moles Na2SO4 = 2.112 moles

300 grams of sodium sulfate represents 2.112 moles

b is the correct answer

mark me brainliest and hope this

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
