Hurricanes, Tornadoes, and Thunderstorms all have low-pressure air.
Answer:
8.98*10^23 molecules CO2
Explanation:
The molar mass of CO2 is 44.0 grams/mol. If we convert 65.8 grams of CO2 into moles, 65.8g CO2 / 44.0g CO2 then we get about 1.49 moles of CO2. We know there are 6.02*10^23 molecules in a mole, so we would just multiply 1.49 mol CO2 * 6.02*10^23 = 8.98*10^23
Answer:
This statement is true.........
That would be 222.0 mm to 4 sig figs
We are given with the mass of Arsine (
The mass of arsine is 15g
there is a relation between moles, mass and molar mass of any compound which is
The molar mass of Arsine = atomic mass of As + 3X atomic mass of H
the molar mass of Arsine = 74.92 + 3X 1 = 77.92 g/mol
Let us calculate the moles as
