Answer:
Mass of carbon = 109.1 g
Explanation:
Given data:
Mass of carbondioxide = 400 g
Mass of carbon = ?
Solution:
Molar mass of carbon = 12 g/mol
Molar mass of CO₂ = 44 g/mol
Mass of carbon in 400g of CO₂:
Mass of carbon = 12 g/mol/44 g/mol × 400 g
Mass of carbon = 109.1 g

Answer:
An element X reacts with oxygen to form XO
and with chlorine to form XCl
. XO
is a white solid that melts at high temperatures (above 1000 degrees C). Under usual conditions, XCl
is a colorless liquid with a boiling point of 58 degrees C.
