4.A mass of one kg of nickels has a monetary value in the US $ of approximately:

a. $1 b. 10 cents c. $10 d. $1000

is it c?

A U. S. nickel has a mass of 5.0 grams. So 1 kg = 1,000 grams and 1000 grams at 5g/nickel must be 200 nickels. How much money would that be at 5 cents/coin?

yes, c is correct.

Oh, I see you're looking for the monetary value of one kilogram of nickels in the US. Well, let me entertain you with a response! The correct answer is b. 10 cents. You see, a kilogram of nickels might be quite heavy, but in terms of dollars, it won't make you a millionaire. So, if you were hoping to find a hidden treasure in that mass of nickels, I'm afraid you'll have to keep searching! Keep laughing and asking me more questions!

To find the monetary value of one kg of nickels, we need to know the weight and value of each nickel.

The weight of a nickel is approximately 5 grams, or 0.005 kg.

Now, we can calculate the number of nickels in one kg:

1 kg / 0.005 kg per nickel = 200 nickels

Next, we can find the value of 200 nickels in US dollars:

200 nickels * $0.05 per nickel = $10

Therefore, the correct answer is c. $10.
