The significant figures has to be rounded off for the given measurement. Concept Introduction: Significant figures: The total number of digits that are recorded for a measurement is named as measurements of number of significant figures. Rules for significant figures: Zero present in the middle of number are always significant Example: The number of significant figures in 4 .803 cm is four. Zero present at the starting of a number are non-significant, they act to find the decimal point. Example: The number of significant figures in 0 .0061g is three. Zero present at the end of the number and after a decimal point are significant. Example: The number of significant figures in 55 .220 K is five. Zero present at the end of the number and before a decimal point are non-significant. Example: The number of significant figures in 34,200 m may be three, four or five. Rounding off the significant figures: If the first digit is less than five, round down by dropping it and all succeeding digits If the first digit is greater than or equal to five, remove five and add one to the digit on the left.

The average micro-nano plastic concentration in bottled water was about 2.4×10^5 particles per liter of bottled water, about 90% of which were nano-sized particles. Assuming that each nanoparticle can be approximated as a sphere with a diameter of 100 nm and that the average density of nanoparticles is 1.2 g/cm^3, estimate the mass of nanoparticles ingested if someone drinks all of their recommended 64 fluid ounces of water per day via bottled water every day for a year. Provide your answer is units of nanograms (ng).

Concept Introduction:

Significant figures:

The total number of digits that are recorded for a measurement is named as measurements of number of significant figures.

Rules for significant figures:

Zero present in the middle of number are always significant

Example: The number of significant figures in 4.803 cm is four.

Zero present at the starting of a number are non-significant, they act to find the decimal point.

Example: The number of significant figures in 0.0061g is three.

Zero present at the end of the number and after a decimal point are significant.

Example: The number of significant figures in 55.220 K is five.

Zero present at the end of the number and before a decimal point are non-significant.

Example: The number of significant figures in 34,200 m may be three, four or five.

Rounding off the significant figures:

If the first digit is less than five, round down by dropping it and all succeeding digits

If the first digit is greater than or equal to five, remove five and add one to the digit on the left.
