Answer:

1. -2, 2. -23, 3. 25

Step-by-step explanation:

1. -2+5x8/-12=  step 1: add -2+5

-2+5=3       step 2: 3(8)

3x8= 24     step 3: 24/-12

24/-12= -2

2. -2(9-4)+3=?  step 1: combine like terms -2(9) and -2(-4)

-18-8+3=?    step 2: combine like terms

-26+3=?      step 3: combine like terms

-23=?

3. 2x + 130=180    step 1: -130 on both sides

   2x = 50              step 2: /2 on both sides

    x = 25

A closed container has 5.04 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10−24 grams.
MatroZZZ [7]

Answer:

The correct option is the last one (0,84 grams, because (5.04 × 1.67) × (10^23 x 10^-24) = 8.4168 x 10^-1))

Step-by-step explanation:

The first step is to think that you have to multiply the number of atoms for the weight of each atom.

When you work with scientific notation, you should solve the operation for numbers and for the ten base. In this case you solve 5.04 x 1.67 and then the product of the ten bases. For this product you have to sum the exponents of the ten base 23 + (-24) = -1.

Summarizing.... 5.04 x 10^23 x 1.67 x 10^-24 = (5.04 x 1.67) x (10^23x10^-24)  ⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 8.4168 x 10^-1

⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 0,84168.
