They are similar because both of them slow things down.
The answer is d, because the simplest form of C4H10 is C2H5 which is the empirical formula
find mol of N2 present using gas law equation
PV = nRT
P = pressure = 688/760 = 0.905 atm.
V = 100mL = 0.1L
n = ???
R = 0.082057
T = 565+273 = 838
Substitute:
0.905*0.1 = n*0.082057*838
n = 0.0905 / 68.76
n = 0.00132 mol N2
Molar mass N2 = 28 g/mol
0.00132 mol = 0.00132*28 = 0.037g N2 gas
Answer:
The answer is
<h2>16.8 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of object = 52.9 g
density = 3.14 g/mL
The volume of the object is

We have the final answer as
<h3>16.8 mL</h3>
Hope this helps you
