Answer:
Mass = 23.36 g
Explanation:
Given data:
Number of particles of CO₂ = 3.20 ×10²³
Mass of CO₂ = ?
Solution:
1 mole contain 6.022×`10²³ particles,
3.20 ×10²³ particles × 1 mol / 6.022×`10²³ particles
0.531 mol
Mass of CO₂:
Mass = number of moles × molar mass
Molar mass = 44 g/mol
Mass = 0.531 mol× 44 g/mol
Mass = 23.36 g
Answer:
sunshine
Explanation:
because it's light u get it from the ecosystem
The correct answer is approximately 1.95g. First, take (1.022*10^10)/(1.277*10^9). This is the same as time elapsed/half-life. This gives you 8, which is the number of half lives. Then multiply mass (500.3g) by (1/2)^8, resulting in 1.95g, which is the answer.
the mass of oxy gas would be 4.03 did i calculate that right?
