Question

What is the volume of water in 150ml of the 35% w/w of sucrose solution with a specific gravity of 1.115?

Answer 1

Answer:108.71 mL

Step-by-step explanation:

Given

Volume of sample V=150 mL

concentration of sucrose solution 35 % w/w i.e. In 100 gm of sample 35 gm is sucrose

specific gravity =1.115

Density of solution
`\rho _s=1.115* density\ of\ water`

Thus

`\rho _s=1.15* 1 gm/mL=1.115\ gm/mL`

mass of sample
`M=1.115* 150=167.25\ gm`

mass of sucrose
`m_s=0.35* 167.25=58.53\ gm`

mass of Water
`m_w=108.71 gm`

Volume of water
`=108.71* 1=108.781 mL`
