Answer:
C.) 3.5 atm
Explanation:
Because you are dealing with pressure and volume, you can use Boyle's Law to help you find the missing variable. The general formula looks like this:
P₁V₁ = P₂V₂
In this formula, "P₁" and "V₁" represent the pressure and volume of the chamber originally. "P₂" and "V₂" represent the final pressure and volume. You have been given the values of all the other variables but "P₂". Therefore, you can plug these values into the formula and simplify to find the final pressure.
P₁ = 1.5 atm
V₁ = 1.4 L
P₂ = ?
V₂ = 0.60 L
P₁V₁ = P₂V₂ <---- Boyle's Law formula
(1.5 atm)(1.4 L) = P₂(0.60 L) <---- Plug in values
2.1 = P₂(0.60 L) <---- Multiply 1.5 and 1.4
3.5 = P₂ <----- Divide both sides by 0.60
Answer:
water, as there is 0.01% of itis left, mainly from polar caps, potable water is present, if it is not used carefully, then there will be no potable water for us to drink
Explanation:
Answer:
162.2 g/mol
Explanation:
Molar mass is defined as the mass in 1 mole of the substance. It is calculated by adding the molar mass of the substituents each multiplied by the subscript they have in the formula.
Thus, To calculate molar mass of nicotine having formula, 
Molar mass of C = 12.0107 g/mol
Molar mass of H = 1.00784 g/mol
Molar mass of N = 14.0067 g/mol
Thus, molar mass of nicotine = 
= 162.2 g/mol
