Answer:

2.17 gm Al

Explanation:

First, find the number of moles . Then multiply by the mole weight of aluminum.

# moles = 4.85 x 10^22 / 6.022 x 10^23 = .08053 moles

.0805 moles * 26.981 gm/mole = 2.173 gm

Why must the mass of magnesium be less than 0.09 g?

SVEN [57.7K]

The mass of magnesium should be less than 0.09g to enable a faster reaction rate. Magnesium reacts to form a white coating around it which stops the reaction. The lesser the gram the faster the reaction before the coating is formed. It is also advisable to use magnesium fillings to increase the rate of reaction.

If the volume of a gas at 0.5 atm changes from 150 mL to 75 mL, what is the new pressure?

nalin [4]

Answer:

<h2>1 atm </h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we're finding the new pressure

$P_2 = \frac{P_1V_1}{V_2} \\$

We have

$P_2 = \frac{0.5 \times 150}{75} = \frac{75}{75} = 1 \\$

We have the final answer as

<h3>1 atm </h3>

Hope this helps you
