Answer:
K2CrO4
Explanation:
To find the empirical formula, we need to divide each element by its atomic mass. The atomic masses of potassium, chromium and oxygen are 39.0983, 51.9961 and 15.999 respectively. We make the divisions as follows:
K = 1.04/39.0983 = 0.027
Cr = 0.70/51.9961 = 0.013
O = 0.86/15.999 = 0.054
We now divide by the smallest which is the number of moles of the Chromium
K = 0.027/0.013 = 2
Cr = 0.013/0.013 = 1
K = 0.054/0.013 = 4 approximately
The empirical formula is thus:
K2CrO4

Answer:
<u>= 14.24g of </u>
<u> is required.</u>
Explanation:
Reaction equation:
→ 
Mole ratio of ammonium carbonate to carbon dioxide is 1:1
1 mole of CO2 - 44g
?? mole of CO2 - 6.52g
= 6.52/44 = 0.148 moles was produced from this experiment.
Therefore, if 1 mole of
- 96.09 g
0.148 mol of
-- ?? g
=0.148 × 96.09
<u>= 14.24g of </u>
<u> is required.</u>
