How many grams is 5.8 moles of hydrochloric acid (HCI)?<br> Answer to the nearest 0.01 g.
Anvisha [2.4K]

Answer:

211.47 grams

Explanation:

We need to set up a dimensional analysis to solve this problem by converting from moles to grams.

First, find the molar mass of HCl. Since the molar mass of H (hydrogen) is 1.01 g/mol and the molar mass of Cl (chlorine) is 35.45 g/mol, then the molar mass of HCl is:

1.01 + 35.45 = 36.46 g/mol

We have 5.8 moles of HCl, so multiply by its molar mass:

(5.8 mol) * (36.46 g/mol) = 211.468 ≈ 211.47 g

The answer is thus 211.47 grams.

Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the expe
Vinvika [58]

Answer:

See explanation

Explanation:

The rate of reaction depends on on the concentration of reactants. As the concentration of reactants increases, the rate of reaction increases likewise.

If we look at the table, we will discover that the concentration of the thiosulphate is increasing because the volume of water added is decreasing. As such, the rate of reaction increases simultaneously.

Since the rate of reaction increases, the time taken for the cross to disappear decreases steadily. Hence, the values in the last column of the table decreases steadily.
