A test light with an electrical resistance of 9.00 S2 draws a current of 1.50 A when
yuradex [85]

Answer:

20.25 W

Explanation:

Applying,

P = I²R.................... Equation 1

Where P = Power, I = current drawn by the test light, R = Resistance of the test light

From the question,

Given: I = 1.5 A, R = 9.00 Ω

Substitute these values into equation 1

P = (1.5²)(9)

P = 2.25×9

P = 20.25 W

What is the molarity when 100 mL of 1.5 M Kcl is diluted to 300 mL?
Phantasy [73]

Formula M1V1 =M2V2

1.5 * 100 = M2 *300

M2 = 1.5*100/300= 0.5.

Answer: the molarity is 0.5M.

A 1 liter solution was diluted to a molarity of 2 M by bringing the volume up to 4 liters. What was the initial molarity of the
kompoz [17]

Answer:

8.0 mol/L

Explanation:

To do this problem you need to use C₁V₁=C₂V₂. C=concentration and V=volume. (Note: you dont want to use M₁V₁=M₂V₂ because this is measuring mass not concentration).

So, V₁= 1.0L

C₂=2 Mol/L

V₂= 4 L

C₁ is unknown.

you would plug this equation in like this:

(C₁)(1.0 L)=(2.0 Mol/L)(4.0L).

Do algebra to get C₁ alone.

C₁=\frac{(2.0 mol/L)(4.0L)}{1.0L} =8.0 mol/L

The liters cancel out and you are left with mol/L or M

I hope this helps! good luck :)
