Answer:
b) 3x10³m³
Explanation:
The volume of each astronaut breathing in m³ is:
500cm³ * (1x10⁻⁶m³ / 1cm³) = 5x10⁻⁴m³
In 1 minute, the volume is:
5x10⁻⁴m³ * 15 = 7.5x10⁻³m³
In 1 hour:
7.5x10⁻³m³ /min * (60min / 1 hour) = 0.45m³/h
In 1 day:
0.45m³/h * (24h / 1 day) = 10.8m³/day
In 1 year:
10.8m³/day * (365 days / 1 year) = 3942m³ = 3.9x10³m³
That is approximately:
<h3>b) 3x10³m³</h3>
Uh I can help you with the converting into moles, 50 grams= 2.775421, sorry if I didn’t help much :/
