A closed container has 6.08 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10–24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
Answers
Answer:
grams.
Step-by-step explanation:
We have been given that a closed container has atoms of a gas. Each atom of the gas weighs
grams.
To find the total mass, in grams, of all the atoms of the gas in the container, we will multiply number of atoms with mass of each atom.
Using exponent property , we will get:
Therefore, the approximate total mass, in grams, of all the atoms of the gas in the container is grams.

Hello!
To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.
C = 2(36)π
C = 72π
Therefore, the circumference of the circle is 72π inches.

D. <-37, 0, -80>;no
Answers
v x w = 8 i - 24 j + 15 k + 10 j - 12 i - 24 k =
= - 4 i - 14 j - 9 k
Answer: D )
2.
v x w = -16 i - 16 j - 18 k + 12 j + 48 i - 8 k =
= 32 i - 4 j - 10 k
Answer: C )
3.
The cross product:
< - 6, 7, 2 > x < 8, 5, -3 > =
= - 21 i + 16 j - 30 k - 18 j - 10 i - 56 k =
= - 31 j - 2 j - 86 k = < - 31, - 2, - 86 >
Vectors are perpendicular if: cos ( u, v ) = 0
< - 6 , 7. 2 > * < -31, - 2, - 86 > = 186 - 14 - 172 = 0
< 8, 5 , - 3 > * < - 31, - 2, - 86 > = -248 - 10 + 258 = 0

What is linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Jamie is 5 yearsolder than Ella. Jamie's age is 11 years, less than three times Ella's age.
The system of equation can be written as:
j = e + 5
j = 3e - 11
Thus, the system of equations are j = e + 5 and j = 3e - 11 we can solve it using the substitution method.

j = 3e - 11 equations
there are different ways of expressing the same value examlpe . 10 = 4 + 6 and 10 = 8 + 2 and 10= 7 + 3 4 + 6 = 8 + 2 =7 + 3 all = 10
using the concept same applies to varibles j = j so, e + 5 = 3e - 1 so, the possible answer would be e + 5 = 3e - 11 to find the value of e .
