Answers
#"51.0 g"# Explanation:
Volume of water
#= 2.00 × 10^3\ "mL"# Mass of water
#"= Volume × Density" = "1 g"/cancel"mL" × 2.00 × 10^3 cancel"mL" = "2.00 kg"#
#%("m/m") = "Mass of solute"/"Mass of solution" × 100#
#2.5 = "m"/"2.00 kg + m" × 100#
#"2m + 5.00 kg = 100m"#
#"m" = "5.00 kg"/98 = "0.0510 kg = 51.0 g"#
