I'm guessing <span>10.6% based on the following information:
</span>
Mass soln = <span>density×volume=1.06×875=927.5<span>g
</span></span><span><span>M<span>NaCl/</span></span><span>Msoln</span></span>×100=<span>%M
which means this:
</span>

%M=98.6927.5×100=10.6

<span>Was this helpful? I hope so.</span>

The rectangular boat shown below has base dimensions 10.0 cm × 8.0 cm. Each cube has a mass of 40 g, and the liquid in the tank

Paladinen [302]

When boat is sunk into the liquid the net buoyancy on the boat is counterbalanced by weight of the boat

So here weight of the boat = Buoyancy force

let say boat is sunk by distance "h"

now we can say

$F_b = \rho * V * g$

$F_b = 1000*0.10 * 0.08 * h * 9.8$

now by above force balance equation we can write

$m*g = F_b$

$0.040 * 9.8 = 1000 * 0.10 * 0.08 * h * 9.8$

$0.040 = 8h$

$h = 5 * 10^{-3} m$

so boat will sunk by total 5 mm distance
