78.2ºF = 25.7ºC
To find the reference angle for -782 degrees, first, convert it to a positive angle by adding 360 degrees repeatedly until the angle falls within the range of 0 to 360 degrees. Adding 360 degrees twice gives us -782 + 720 = -62 degrees. Now, adding another 360 degrees results in -62 + 360 = 298 degrees. The reference angle is found by subtracting 298 degrees from 360 degrees, which gives us a reference angle of 62 degrees.
20 percent of 782 = 156.420% of 782= 20% * 782= 20%/100% * 782= 1564/10 or 156.4
782 into a fraction = 782/1
782 = 782/1

To find the number of moles of H2, we need to use the ideal gas law equation: PV = nRT. Convert 0.845 L to 0.845/22.4 = 0.0377 moles. Convert 782 mmHg to atm by dividing by 760: 782/760 = 1.03 atm. Plug in the values and solve for n: n = (1.03 atm * 0.0377 moles) / (0.0821 Latm/(molK) * 298 K) ≈ 0.0016 moles of H2.
