The two significant digits are 8 and 5. Leading 0s are place holders and are not significant.
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
There are two significant figures. In scientific notation 0.032 = 3.2 x 10^-2 → it has 2 sig fig.
The number 151.208, when expressed to two significant figures, is 150. This is because the first two significant figures are '1' and '5', and rounding the next digit (which is '1') leads to a decrease in the last significant figure. Therefore, the rounded value is 150.
460. (the period/decimal point is necessary; otherwise 460 would be considered two significant figures)
There are more significant digits in this number than four. The leading zero before the decimal point is not deemed insignificant nor are any of the numbers proceeding it.In 1600.00 the proceeding two zeros after 1600 are insignificant. However, 1600.001, all numbers are significant.
4647 is 4600 to 2 sig fig.
71372 to 2 sig fig is 71000
yes 100 has only one sig fig
It is not always expressed in 2 sig figs. The number of sig figs depends on the accuracy of your measurements of mass and volume to calculate the density as well as any variables that you are expected to use the density with. There is no point in having a density expressed to 15 significant figures if then you are going to multiply it by volume expressed to 1 sig fig to determine the mass.
The first two sig fig are 4.4; the third is '4' which is less than 5, so don't round up: 4.449 → 4.4 to 2 sig fig.
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
The atomic mass of Cu-63 should be expressed to two significant figures, which are 63.
2nd sig fig is 5, next digit (3rd sig fig) is 2 which is less than 5, so round down; ⇒ 1.5255698 = 1.5 to 2 sig fig.
It is: 62 kg
There are two significant figures. In scientific notation 0.032 = 3.2 x 10^-2 → it has 2 sig fig.
To one sig fig, 300 To two sig figs, 310 To three sig figs, 314
The number 151.208, when expressed to two significant figures, is 150. This is because the first two significant figures are '1' and '5', and rounding the next digit (which is '1') leads to a decrease in the last significant figure. Therefore, the rounded value is 150.
