Question

What mass of mass of maltose, C12H22O11 is dissolved in 725 mL of 0.118 M maltose solution? Atomic mass of carbon: 6; atomic mass of hydrogen: 1; atomic mass of oxygen: 16.

Answer 1

Molar mass = $6(12)+1(22)+16(11)=270$

Moles = $\frac {725}{1000}×0.118=0.0856 moles$

Mass = $0.0856×270=23.112grams$
