The mass of 6.12 moles of arsenic (As) is calculated to be approximately 459g.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the number of moles of a substance by its molar mass. That is;
Mass of Arsenic = no. of moles of As × molar mass of As.
According to this question, 6.12 moles of arsenic was given and its molar mass is 74.92g/mol.
Mass of As = 6.12 mol × 74.92g/mol
Mass of As = 459g
Therefore, the mass of 6.12 moles of arsenic (As) is calculated to be approximately 459g.

where are the chemical reactions and their properties to match ?????????
<h3><u>Answer;</u></h3>
At room temperature, the solubility of which solute in water would be most affected by a change in pressure?
<h3><u>Explanation;</u></h3>
- As the pressure on a gas confined above a liquid increases, the solubility of the gas increases in the liquid.
- Carbon dioxide gas is most soluble in water under conditions of high pressure and low temperature.
- The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water is used will be less compared to warm water.
