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

pentagon [3]

Answer:108.71 mL

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 $\rho _s=1.115\times density\ of\ water$

Thus

$\rho _s=1.15\times 1 gm/mL=1.115\ gm/mL$

mass of sample $M=1.115\times 150=167.25\ gm$

mass of sucrose $m_s=0.35\times 167.25=58.53\ gm$

mass of Water $m_w=108.71 gm$

Volume of water $=108.71\times 1=108.781 mL$

Genrish500 [490]

<span>The correct answer is C. divergent plate. That's because the plates diverged, that is, they separated. When they moved away from each other, the sea filled the hole. The opposite would be convergent if two plates moved towards each other and squished out a sea. Transform would be if it changed from one form to another.</span>
