Find the volume of 20.0 g of benzene. It's density is 0.88g/mL
damaskus [11]
d=0,88\frac{g}{mL}\\
m=20g\\\\
d=\frac{m}{V} \ \ \ \Rightarrow \ \ \ V=\frac{m}{d}\\\\\
V=\frac{20g}{0,88\frac{g}{mL}}\approx22,73mL

Write a balanced chemical equation for the reaction. na2co3 and agno3
ahrayia [7]
The equation of the reaction is:
Na2CO3 + AgNO3 → NaNO3 + Ag2CO3
but this equation, not a balanced equation so let's make it a balanced equation:
- we will start with Na number of atoms, we should make the Na atom number is equal on both sides.So we put 2 NaNO3 instead of NaNO3
- and then the Ag atom, we put 2AgNO3 instead of AgNO3 to make the number of Ag on each side are equals.
So the final balanced equation for this reaction is:
Na2CO3(aq) + 2AgNO3(aq) → 2NaNO3(aq) + Ag2CO3(s)
SO know we have number of Na on each side = 2
number of Ag on each side = 2

A 5.0 gram sample of lead and a 3.2 g sample of iron are placed into 367 mL of water. What will be the new volume level of water
olasank [31]
Volume = mass/density 
Lead: v=5.0g/11.34g/cc = 0.440cc
For lead, the new volume level of water will be 367+0.440= 367.440ml

Iron: v=3.2g/7.874g/cc = 0.406cc
For Iron, the new volume level of water will be 367+0.406= 367.406ml 

If you add both, then it will be 367+0.406+0.440= 367.846 mL

First find the volume of each sample and then add that to 367ml of water. 

I hope that helps.
