How much malt sugar (C12H22O11) would you need to make a 4-M solution in water?
2 answers:
Answer:
1368 grams.
Explanation:
Molarity is defined as number of moles of solute present in one litre of solution. 1-M means 1 mole of solute is present in 1 litre of solution.
4-M solution means 4 moles of solute is present in 1 litre of solution.
Molar mass of =
grams.
as molar mass of carbon,hydrogen and oxygen atoms are 12,1 and 16 grams respectively.
Since molar mass of is 342 grams,
1 mole of it weighs 342 grams and 4 moles of it weighs grams.
Hence we need 1368 grams to make a 4-M solution of .

The mass of I₂ that contains 2.57×10²⁵ molecules is 10843.52 g
From a detailed understanding of Avogadro's hypothesis, we understood 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of I₂ also 6.02×10²³ molecules i.e
<h3>6.02×10²³ molecules = 1 mole of I₂</h3>Recall:
1 mole of I₂ = 2 × 127 = 254 g
Thus,
<h3>6.02×10²³ molecules = 254 g of I₂</h3>With the above information, we can obtain the mass of I₂ that contains 2.57×10²⁵ molecules. This is illustrated below:
6.02×10²³ molecules = 254 g of I₂
Therefore,
2.57×10²⁵ molecules =
Thus, the mass of I₂ that contains 2.57×10²⁵ molecules is 10843.52 g
