What volume is occupied by 0.104 mol of helium gas at a pressure of 0.91 atm and a temperature of 314 K ?
Aleksandr-060686 [28]

Answer:

The volume will be "2.95 L".

Explanation:

Given:

n = 0.104

p = 0.91 atm

T = 314 K

Now,

The Volume (V) will be:

= \frac{nRT}{P}

By putting the values, we get

= \frac{0.104\times 0.0821\times 314}{0.91}

= \frac{2.6810}{0.91}

= 2.95 \ L

Question 4<br> Calculate the nlass of 7.1 x 1024 formula units of magnesium hydroxide, Mg(OH),.
faust18 [17]

its me again this is how you find the answer. note: i dont have the periodic table to see the exact atomic mass to find the molar mass however this is the answer:

so the actual formula is Mg(OH) with a 2 as a subscript because there are 2 Mg. so with Mg(OH)2 the Molar mass is 58.32g/mol. 58.32 g/mol x 7.1x1024 = 4.1x1026g

Magnesium combines with oxygen to form magnesium oxide. If 10.57 g of
Phantasy [73]

The total mass is 10.57+6.96=17.53 g.

So, the percent by mass of magnesium is (10.57)/(17.53) * 100 = <u>60.3%</u>

<u />

The percent by mass of oxygen is (6.96)/(17.53) * 100 = <u>39.7%</u>
