Given the following mixture of two compounds 20.00 g of X (MW =83.00 g/mol) and 880.00 mL of Y (72.00 g/mol))(density 0.881 g/mL), calculate the molarity of X.

moles of X = 20.0g / 83.00 g/mol = 0.241 moles
volume of Y = 880.0 mL
molarity of X = moles / liter = 0.240 moles /0.880L = 0.273M
volume of Y = 880.0 mL
molarity of X = moles / liter = 0.240 moles /0.880L = 0.273M
