1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.

Determine the number of pictures
First, we need to calculate the length of the available space
This is calculated by subtracting the width of the window from the width of the wall.
Convert fraction to decimal
Since, the pictures are placed side by side.
This means that, there's no empty space between them.
Number of pictures is:
Convert feet to inches
Answer:
30=8x
Step-by-step explanation:
lizabeth cant climb for 4.5 hrs because if you divide 30 by 8 you get 3.75. so Lizabeth can climb for 3.75 hrs using only her $30 gift card
Answer:
The equation is 
x = 
Step-by-step explanation:
The Equation is formed from two sides equal to each other
- In the algebraic statement "is" means equal
- In the algebraic statement "of" means times (×)
∵ One eighth means 
∴ Negative one eighth means
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number = × (x)
∴ Negative one eighth of a number = x
∵ Negative one eighth of a number is
→ "is" means equal, so the left side is x and the right side is
∴ x = ⇒ Equation
∴ The equation is x =
