Did you mean milliliters? if so your answer would still be 876 because they are equal. I don't think it is possible to convert millimeters and grams :)

If you have 2.4L of SO2 gas (at STP) how many moles of sulfur dioxide do you have?

Andru [333]

Answer:

0.107 mole of SO2.

Explanation:

1 mole of a gas occupy 22.4 L at standard temperature and pressure (STP).

With the above information, we can simply calculate the number of mole of SO2 that will occupy 2.4 L at STP.

This can be obtained as follow:

22.4 L contains 1 mole of SO2.

Therefore, 2.4 L will contain = 2.4/22.4 = 0.107 mole of SO2.

Therefore, 0.107 mole of SO2 is present in 2.4 L at STP.

Consider the reaction of 35.0 g of iron as follows:

77julia77 [94]

Explanation:

4Fe + 3O2 --> 2Fe2O3

Mass of iron = 35g

How many moles of iron react?

The relationship between mass and moles is given as;

Moles = mass / Molar mass

Molar mass of iron = 56g/mol

Number of moles = 35 / 56 = 0.625 mol

How many moles of oxygen molecules must react?

From the equation of the reaction;

4 mol of Fe reacts with 3 mol of Oxygen molecule

0.625 mol would react with x mol?

4 = 3

0.625 = x

x = 0.625 * 3 / 4 = 0.46875 mol

How many moles of product form?

From the equation of the reaction;

4 mol of Fe reacts to form 2 mol of Fe2O3

0.625 mol would form x mol of Fe2O3

4 = 2

0.625 = x

x = 0.625 * 2 / 4 = 0.3125 mol

What mass of product forms?

Moles = mass / Molar mass

Mass = Molar mass * Moles = 159.69 g/mol * 0.3125 mol = 49.9g
