A closed container has 4.02 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10^−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container? 6.71 grams, because (4.02 ⋅ 1.67) ⋅ (10^23 ⋅ 10^−24) = 6.7134
5.69 grams, because (4.02 + 1.67) ⋅ (10^23 ⋅ 10^−24) = 5.69
0.67 grams, because (4.02 ⋅ 1.67) ⋅ (10^23 ⋅ 10^−24) = 6.7134 ⋅ 10^−1
0.57 grams, because (4.02 + 1.67) ⋅ (10^23 ⋅ 10^−24) = 5.69 ⋅ 10^−1
2 answers:
Total mass of the atoms=number of atoms * weight of an atom Total mass of the atoms=(4.02*10²³)*(1.67*10⁻²⁴)=(4.02*1.67)*(10²³⁻²⁴)= =6.7134*10⁻¹Answer: 0.67 grams, because (4.02*1.67)*(10²³*10⁻²⁴)=6.7134*10⁻¹
Answer: 0.67 grams, because
Step-by-step explanation:
Given : The number of atoms in a closed container =
The weight of each atom of the gas =
We know that the total mass of atoms of the gas in the container
Hence, the approximate total mass of all the atoms of the gas in the container =0.67 grams

Answer:
y=4/5x+1
Step-by-step explanation:
y=mx+b
m = slope = 4/5
b = y-intercept= 1
y=4/5x+1
3(n+2) ← algebraic expression
4 2/3 = 14/3
15 = 15/1
14/3 * 15/1 = 14*15=210, 3*1 = 3
210/3 = 70
answer is 70
