Answer:
2.52kg
Explanation:
80mm = 8 cm
0.15m = 15 cm
volume of the container = 10m × 8cm × 15cm
= 1200 cubic centimetres
mass = density × volume
= 2.1 × 1200
= 2520g
2520/ 1000
= 2.52kilograms
Answer: option B.olive oil.Explanation.The general rule of thumb when you analyze the ability of a solvent to dissolve a solute is that lke dissolves like.
That means:
1) polar solvents dissolve ionic or polar solutes
2) Non-polar solvents dissolve non-polar solutes
3) Non-polar solvents do not dissolve polar and ionic solutes
4) Polar solvents do not dissolve non-polar solutes.
There are exceptions, but the rule is applicable in here.
<span>
A. table salt: it is NaCl, a ionic compound, so the water which is a polar solvent will dissolve the table salt.
B. Olive oil: the oils are non-polar organic compounds, so it will not be dissolved in a polar solvent.
C. Vinegar: vinegar is acetic acid, which is a polar organic compound, so it will be dissolved in water.
D. Sugar: sugar (sucrose) is a polar organic compound, so it will get dissovled in water.</span>
Answer:
Explanation:
Hello,
In this case, we are asked to compute the by mass percent for the given 3.2 g of ethylene glycol in 43.5 g of water. In such a way, since the by mass percent is computed as follows:
Whereas the solute is the ethylene glycol and the solvent the water, therefore we obtain:
