Answer:5
Explanation:In order to be able to say how many sig figs are used for the measurement 811.40 g, you need to know that
<span><span>
non-zero digits are always significant</span><span>
a trailing zero that follows a decimal point and a non-zero digit is always significant</span></span>
In your case, the measurement
<span>811.40</span>
has four non-zero digits and one significant trailing zero.
<span><span><span>8,1,1,4</span>→</span> non-zero digits<span><span>8,1,1,</span>0→</span> significant trailing zero</span>
Therefore, you can say that this measurement has <span>five significant figures</span>
<span>811.40→</span> <span>five significant figures</span>
Answer : The mass of 
required is, 61.82 grams.
Explanation :
First we have to calculate the moles of 
Now we have to calculate the moles of .
The balanced chemical equation is:
From the balanced reaction we conclude that
As, 1 mole of react with 6 mole of
So, 0.322 moles of react with 
moles of
Now we have to calculate the mass of
Molar mass of = 32 g/mole
Therefore, the mass of required is, 61.82 grams.
