<span>You are given O2 and C3H8, this is a combustion reaction. The chemical reaction is C3H8 + 10O2 à 3CO2 + 4H2O. You are also given the molar mass of O2 which is 32.00 g/mol and C3H8 which is 44.1 g/mol. You are required to find the mass of O2 in grams. Since you have the reaction, oe mole of C3H8 is required to completely react 10 moles of O2. So,</span>  

0.025g C3H8(1 mol C3H8/44.1 g C3H8)(10 mol O2/1 mol C3H8)(32 g O2/1 mol O2) = <u>0.1802 g O2 </u> <span> </span>

What is the mass of 2.30 ×1022 molecules of NaOH
viva [34]
Molar mass of NaOH = 39.997 g/mol

39.997 g  ---------- 6.02x10²³ molecules
   g --------------- 2.30x10²² molecules

mass = 2.30x 10²² * 39.997 / 6.02x10²³

mass = 9x199^24 / 6.02x10²³

mass = 15.280 g

hope this helps!

5. What is required to cause acceleration?<br> SN-&gt;
exis [7]

Answer:

The law states that unbalanced forces cause objects to accelerate with an acceleration that is directly proportional to the net force and inversely proportional to the mass. Acceleration is caused both by magnitude and direction of velocity.
