Answer:
123.0*12.35/(0.05*6.049)
first do in small bracket 123.0*12.35/0.30245
and then divide 123.0*40.83319557
and multiply 5022.483055
ANSWER:
2.65 g H2O
Explanation:
6.49g (co2) / 44.009g (co2) x 1 mol (co2) / 1 mol (h2o) x 1 mol (h2o)
=0.147 mol H2O
0.147 mol (H2O) / 1 mol (h2o) x 18.015 g (h2o)
=2.65 g H2O
Answer:
5.9405*10^14 Hz
Explanation:
Remember the equation c=v*λ
v=frequency
λ=wavelength
By manipulating the equation, we can get it in terms of frequency:
c/λ=v
Now convert wavelength to meters (1nm=m*10^-9)
5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)
Use the manipulated equation:
(3.00*10^8)/(5.05*10^-7), which yields:
5.9405*10^14 Hz (or s^-1)
