Hydrogen gas has a density of 0.090/gL, and at normal pressure and 4.31°C one mole of it takes up 22.4L. How would you calculate the moles in 570.g of hydrogen gas? Set the math up. But don't do any of it. Just leave your answer as a math expression.

Also, be sure your answer includes all the correct unit symbols.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
