It’s the measure of spaces between objects. It affects groundwater infiltration by having more water fill the spaces between it. For example, is you have bigger rocks the spaces between it are bigger therefore the groundwater infiltration rate is faster. If the rocks are smaller, they are tightly packed and it’s not easy for groundwater infiltration.

krok68 [10]

Number of significant figures will be 1

Given:

weight of acetylsalicylic acid = 0. 4g

To Find:

significant figures

Solution: Significant figures are the digits of value which carry meaning towards the resolution of the measurement. They are also called significant figures in chemistry. All the experimental measurements have some kind of uncertainty associated with them.

When we convert 0.4g acetylsalicylic acid to mg we get value 400mg

when we convert 400mg to gram we get value of 0.4 gram

Since 0 before a decimal is not significant so there is only one significant figure that is 4
