Considering the definition of percent yield, the percent yield is 76%.
<h3>Percent yield</h3>
The percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.
The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:
where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
<h3>Percent yield in this case</h3>
In this case, you know:
- actual yield= 0.532 moles
- theorical yield= 0.700 moles
Replacing in the definition of percent yield:
Solving:
<u><em>percent yield= 76%</em></u>
Finally, the percent yield is 76%.

They contain the same number of molecules; however, the masses can differ depending on the molar masses of the substances.
The answer is: the percent composition of chromium is 20.52%.
Ar(Cr) = 52; atomic mass of chromium.
Mr(BaCrO₄) = 253.3; molecular mass of barium chromate.
ω(Cr) = Ar(Cr) ÷ Mr(BaCrO₄) · 100%.
ω(Cr) = 52 ÷ 253.3 ·100%.
ω(Cr) = 20.52%; the percent composition of chromium in barium chromate.

odyssey ware
Answer:
If more solute is added and it does not dissolve, then the original solution was saturated
If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturate
