Give the number of significant figures: 369,132,000 sec a. 0 b. 6 c. 9

A. 6

Explanation:

369 132 000 s

The important rules are

•Digits other than zero are significant

•Trailing zeroes before the decimal point are not significant

The decimal point is after the last zero, so the three zeroes are not significant,

Thus, the underlined digits in 369 132 000 are significant.

There are six significant figures in the measurement.

your answer is c

hope i ! ; )

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
