What is the answer, with the correct number of significant figures, for this problem? 4.392g + 102.40g + 2.51g =

Answer : The correct answer will be,

Explanation :

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

The rule apply for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

The given expression is:

In the given expression, 4.392 has 4 significant figures, 102.40 has 5 significant figures and 2.51 has 2 significant figures. From this we conclude that least precise number present after the decimal point is 2.

Thus, the answer will be

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
