Q. What is the mass in grams of one mole of any substance know as
A. Molar Mass
Answer:
New pressure is 5.40 atm
Explanation:
When T° and moles remain constant, we should use these relation to determine pressure, or also volume
P₁ . V₁ = P₂ . V₂
1.80 atm . 3L = P₂ . 1L
(1.80 atm . 3L ) / 1L = P₂
5.40 atm = P₂
Answer
A. molecules
Explanation
When atoms or elements combine, they are called molecules. When molecules combine they form compounds.
Answer:
Sound waves and some earthquake waves are longitudinal waves.Ocean, light, and other earthquake waves are transverse waves
Explanation:
The liters in 3.25 g of ammonia 4.28 L
<u><em>calculation</em></u>
Step 1: find moles of ammonia
moles = mass÷ molar mass
From periodic table the molar mass of ammonia (NH₃) = 14 +(1×3 ) = 17 g/mol
3.25 g÷ 17 g/mol = 0.191 moles
Step 2: find the number of liters of ammonia
that is at STP 1 moles = 22.4 L
0.191 moles = ? L
<em>by cross multiplication</em>
={( 0.191 moles ×22.4 L) / 1 mole} = 4.28 L
