The correct answer here would be C.
First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and the balanced chemical reaction,
theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)
theoretical amount of Na2O = 72.9 g of Na2O
Calculation of percent yield,
% yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
% yield = 84.75%
Answer: 84.75%
Answer:
The answer to your question is: density = 0.5 g/ml
Explanation:
Data
Volume = 10 ml
mass = 5 g
Density = ?
Formula
density = mass / volume
Substitution
density = 5/ 10
density = 0.5 g/ml
The value of the given equation i.e. (4.123 × 0.12) + 24.2 is 24.7.
Given that,
- The equation is (4.123 × 0.12) + 24.2.
According to the BODMAS rule, first, we have to multiply 4.123 with 0.12 after that add the 24.2 to the value that comes.
So,
= (4.123 × 0.12) + 24.2
= 0.49476 + 24.2
= 24.69
= 24.70
Therefore we can conclude that the value of the given equation i.e. (4.123 × 0.12) + 24.2 is 24.7.
