Hello, here’s the answer to your question. Converting ammonia to nitrate, which is absorbed by plants
To calculate number of moles, all you do is divide the given mass by the molecular molar mass:
<span>i.e. 125g / 18g = 6.94444g </span>
<span>Therefore, your answer is (a) 6.94 g</span>
2HgO=2Hg + O2
433,18 g. = 32 g
x. = 250 g
x= 3 384,21875 g of HgO is needed
1023 molecules or atoms depending on substance
Answer:
