A closed container has 5.04 ⋅ 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:

Step-by-step explanation:

Each atom of the gas weighs 1.67 ⋅ 10−24 grams. 6.71 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71. ... 0.67 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71 ⋅ 10−1.

What is 68,642 rounded to the nearest thousand?

Answers

68,642 rounded to the nearest thousand is 69,000.

It's because 68,642 is closer to 69,000 than to 68,000.

I hope it will help you and give a clue for rounding numbers in the future ;)
The rule of rounding numbers up is if it's 5 or up, round it.  Since your number is 68,642, it would round to 69,000.  Because the 6 in the hundreds place is greater than 5.
