An object with a density of 3.7kg/m^3 has a mass of 2.5g. What's the volume in mL?
valentinak56 [21]
d=3,7\frac{kg}{m^{3}}=3,7\frac{1000g}{1000000mL}=0,0037\frac{g}{mL}\\
m=2,5g\\\\
d=\frac{m}{V} \ \ |*V\\
dV=m \ \ |:d\\
V=\frac{m}{d}=\frac{2,5g}{0,0037\frac{g}{mL}}\approx 675,68mL

You are asked to weigh approximately 0. 4g of acetylsalicylic acid to the nearest mg. When you enter the data in grams in your l
julia-pushkina [17]

Number of significant figures will be 1.

Given:

weight of acetylsalicylic acid = 0. 4g

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.

<h3>How do you determine the number of significant figures?</h3>
  • The zero to the left of a decimal value less than one is meaningless.
  • All trailing zeros that are placeholders are meaningless.
  • The presence of zeros between non-zero numbers is significant.
  • Non-zero numbers are all significant.
  • If a number contains more digits than the desired number of significant digits, it is rounded.
<h3>Why 'Hidden Figures' is so important?</h3>

It's an important story for a variety of reasons, and it comes at a time when people are looking to Hollywood more than ever to tell stories that represent them. Hidden Figures is that movie for many, and it's critical that everyone sees these women in action. This is why. This film tells a story that you've probably never heard before.
