60.2 mg = _____ g

Answers

Answer:

60.2 mg is equal to 0.0602 g.

Explanation:

Given = 60.2 mg

To find : 60.2 mg = ? g

Solution:

We know that in 1 gram there are 1000 milligrams.

1 g = 1000 mg

Then in , 1 mg = 0.001 g

So, 60.2 mg = 60.2 mg 0.001 g=0.0602 g

the question is 0.0602

There are about 1 760 000 000 000 000 000 000 molecules of sucrose in 1 g of table sugar. Expressed in scientific notation, what is the number of molecules in 1 g of sugar? A) 1.76 x 10-22 B) 1.76 x 10-20 C) 1.76 x 1021 D) 1.76 x 1022

Answers

The correct answer from the given choices is A. One gram of table sugar is equal to 1.76 x 10^21 molecules of sucrose. Scientific notation is a method that scientists use to easily handle numbers that are very large or very small.

Answer:

The correct answer is option c.

Explanation:

Hello!

Let's solve this!

To write a number in scientific notation, we look for a number between zero and nine. Then we count the number of times we ran the point to reach that number. If we run the point to the right, the exponent is negative. If we run the point to the left, the exponent is positive.

In this case the number is: 1 760 000 000 000 000 000 000

We choose the number 1.76

We run the point 21 times to the left, so the exponent is positive.

The solution is $1.76*10^(21)$
