Mg = 24.3 g/mol
23.5 g / 24.3 g/mol = 0.97 mol Mg
We can apply Charles's law:
V/T = constant
V₁/T₁ = V₂/T₂
V₂ = 3 x 200 / 300
V₂ = 2 L
Answer:
The molecular geometry of SO3 is trigonal planar.

Look at the Lewis
Answer:
2,500,000 litres or 2.5 megalitres of water.
Olympic size pools measure: 50 metres long, 25 metres wide, and a minimum of 2
metres deep.
(25m x 50m x 2m = 2,500m3; 1L = 0.001m3 so 2,500 x 1000 = 2,500,000L)
660,430 gallons of water.
50 meters = 164.041995 feet (a)
25 meters = 82.0209975 feet (b)
2 meters = 6.5616798 feet (c)
Volume = (a) * (b) * (c) = 88,286.66721 cubic feet Explanation:
Answer:
1.99moles
Explanation:
molar mass of HCl = 1 + 35.5 = 36.6 g/mol
reacting mass of HCl = 72.9 grams
number of moles= reacting mass÷molar mass
= 72.9÷36.6
=1.99mol
