How many grams are in 275 moles of potassium sulfate (K_(2)SO_(4)) (moles to mass/grams)

To find the mass in grams of 2.75 moles of potassium sulfate (K2SO4), we need to calculate the molar mass of K2SO4 and then multiply it by the number of moles.The molar mass of K2SO4 is calculated as follows:- Potassium (K): 39.10 g/mol- Sulfur (S): 32.07 g/mol- Oxygen (O): 16.00 g/molMolar mass of K2SO4 = (2 * 39.10) + 32.07 + (4 * 16.00) = 174.27 g/molNow, we can calculate the mass of 2.75 moles of K2SO4:Mass = Molar mass * Number of molesMass = 174.27 g/mol * 2.75 molesMass = 479.24 gramsTherefore, there are 479.24 grams in 2.75 moles of potassium sulfate (K2SO4).
