Answer:
Explanation
To get a mole of a compound just add up the molar mass
For example: O2
1 mole of oxygen is 16g
1 mole of O2= 32g
You can find the molar mass of each individual element on the periodic table of elements
Answer:
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.
Remember to keep both cold and hot water dripping during these frigid temperatures. We know to keep the faucets dripping when temperatures dip below freezing, but experts say you need to keep both cold and hot water open
Hope this helps :) pls give brainliest
Explanation:
By applying ideal gas equation,
[tex]P\times V=n\times R\times T[\tex]
Where, P= pressure of gas
V=volume of gas
R=Gas constant
n=Number of moles of gas
T=Temperature
At STP, each gas has a defined value of pressure, volume and temperature.
P= 1 atm
R=0.0821 L atm mol⁻¹ K⁻¹
T= 0°C or 273 K
Putting all the values in the equation will give:
[tex]1\times V=0.98\times 0.0821\times 273[\tex]
V = 22 L
So the answer is 22 L.
