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
The answer is C, good luck mate
Formula M1V1 =M2V2
1.5 * 100 = M2 *300
M2 = 1.5*100/300= 0.5.
Answer: the molarity is 0.5M.
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=
The liters cancel out and you are left with mol/L or M
I hope this helps! good luck :)
