1. If 80.0 ml of 3.00 M HCl is used to make a 100. ml of dilute acid, what is the molarity
Aleonysh [2.5K]

<u>We are given:</u>

M1 = 3 Molar        V1 = 80 mL

M2 = x Molar        V2 = 100 mL

<u>Finding the molarity:</u>

We know that:

M₁V₁ = M₂V₂

where V can be in any units

(3)(80) = (x)(100)

x = 240/100                                          [dividing both sides by 100]

x = 2.4 Molar

Use the formula: PV=nRT<br><br> If P=12, V=22.4, R=.0821 and T=100, then what would n=?
Lina20 [59]
PV=nRT \\ (12)(22.4)=n(.0821)(100) \\ 268.8=8.21n \\ 268.8/8.21=8.21n/8.21 \\ n=32.74
n ≈ 32.74
