To take the percent by mass of this element, we use the
formula:
% mass = (mass of element / mass of ore) * 100%
% mass = (47.5 g / (660 kg * 1000 g / kg)) * 100*
<span>% mass = 7.20 x 10^-3 %</span>
A chemical reaction must occur for a compound to have different properties.
Answer:
0.1186mol Hg
Explanation:
To calculate the number of moles using the mass we divide the mass by the molar mass.
23.79g ÷ 200.59g/mol = 0.1186mol Hg

Answer:
In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
