A force of 350 N causes a body to move with an acceleration of 10 m/s2. What's the mass of the body?
Scrat [10]
You have to use the equation F=ma and solve for m to get m=F/a.
m=mass in kg
F=force (in this case 350N)
a=acceleration (in this case 10m/s²)
when you plug everything in you should find that m=35kg

I hope this helps.

A compound in a copper ore has the following percentage composition by mass:
AveGali [126]
1) since we are given percentages, we can assume we have 100 grams of the molecule.

55.6 % Cu ----> 55.6 grams Cu
16.4 % Fe------> 16.4 grams Fe
28.0% S--------> 28.0 grams S

2) convert each gram to moles using the molar masses given

55.6 g Cu \frac{1 mol}{63.5 g} = 0.876 mol Cu
16.4 g Fe \frac{1 mol}{56.0 g} = 0.293 mol Fe
28.0 gS \frac{1 mol}{32.0} = 0.875 mol S

3) we divide the smallest value of moles (0.293) to each one.

Cu --> 0.876 / 0.293= 3
Fe---> 0.293 / 0.293= 1
S-----> 0.875 / 0.293= 3

4) let's write the empirical formula

How many moles of oxygen atoms are in 1.2x10^25 diphosphorus pentoxide molecules
insens350 [35]

Answer:

19.9 atoms

Explanation:

Grams --- Moles --- Atoms

You're converting from atoms (molecules) to moles.

You do not have to calculate the mass of "di phosphorus pentoxide."

Since you're already given 1.2x10^25 atoms, you start with that. You need to cancel out the atoms, so you need Avogadro's number as shown in the image.

(This has nothing to do with the problem) But in case if you're wondering, the "di" in phosphorus means there's 2 phosphorus and the "pent" means that there are 5 oxygens. So P2O5. Go to your periodic table, multiply their respective atomic masses. You would multiply phosphorus twice and oxygen 5 times. And add them up to get the overall mass.

I hope this helped!
