How many milligrams of sodium phosphate are needed to make 0.0893 L of a 2.46 M solution? Supply the answer in scientific notation.

Answer value

Answer 1

molar mass sodium phosphate (Na₃PO₄) = 163.9 g/mol

0.0893 L x 2.46 mol / L x 163.9 g/mol x 1000 mg/g = 36,005 mg Na₃PO₄ = 3.60x10⁴ mg (3 sig. figs.)
