Answer:
B
Explanation:
because every Chinese shar-pei has wrinkled skin.
Given:
Molar mass of CO2 = 44.01g/mol
3.21x10^25 molecules of CO2
Required:
Mass of CO2
Solution:
Avogadro’s number states that
for every mole of atom, there are 6.023x10^23 units of atom. The units may be
formula units, atoms. In here, you need to divide 3.21x10^25 molecules of CO2
to 6.023x10^23 molecules per mole.
3.21x10^25 molecules of CO2 / 6.023x10^23
molecules per mole = 53.30 moles CO2
53.30 moles CO2 (44.01g/mol CO2)
= 2346 g of CO2
Answer:
Oxygen - Proportions increased as plants released this gas into the atmosphere.
Water Vapor - Proportions decreased as this lighter gas was blown away by solar winds.
Hydrogen - Proportions increased as this gas was released through volcanic eruptions.
Ammonia - Proportions decreased as it reacted with other elements to form nitrogen.
Carbon Dioxide - Proportions decreases as plants used this gas during photosynthesis.
