1) CO (g) + 2H_{2}(g) ---> CH_{3}OH (g)

Moles of methanol = 208 kg CH_{3}OH * \frac{1000 g}{1 kg} * \frac{1 mol CH_{3}OH}{32.04 g CH_{3}OH} = 6492 mol CH_{3}OH

Mass of H_{2} that would produce 208 kg methanol =

6492 mol CH_{3}OH * \frac{2 mol H_{2}}{1 mol CH_{3}OH} * \frac{2.02 g H_{2}}{1 mol H_{2}} * \frac{1 kg}{1000 g}=  26.2 kg H_{2}

2) Mass of sodium = 1.3 * 10^{21} atoms Na * \frac{1 mol Na}{6.022* 10^{23}atoms Na} * \frac{22.99 g Na}{1 mol Na} = 0.0496 g Na

3) Mass of mercury = 1.2 mL * 13.6 \frac{g}{mL} = 16.32 g

Number of atoms of mercury = 16.32 g Hg * \frac{1 mol Hg}{200.59 g Hg} * \frac{6.022* 10^{23} atoms Hg}{1 mol Hg} =   4.9 * 10^{22} atoms Hg

Determine the latitude and longitude of the location A
malfutka [58]

Answer:

Latitude: 30\° N

Longitude: 45\° W

Explanation:

Lets begin by explaining the meaning of latitude and longitude as geogrephical coordinates:

Latitude is the angular distance between the equatorial line, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.  

In this sense latitude 0\° refers to the equatorial line that divides the Earth in two hemispheres (North and South).

Longitude represents the specific east–west position of a point on the Earth's surface, being longitude 0\° the prime meridian or Greenwich meridian.

So, according to the figure, where the model of the Earth is divided by latitude lines separated by 10\° and the longitude lines separated by 15\°; we only have to count the lines from the equator to the line where the point A is, and count the lines fromo the Prime meridian to the line where point A is located.

Hence, point A location is:

Latitude: 30\° N

Longitude: 45\° W

A liquid has a density of 1.17 g/cm3, how many liters of the liquid have a mass of 3.75 kg
Luda [366]
<span>There are 1000 cm3 in 1 liters. Hence 1 liter of the liquid would weigh: 1000 cm3 x (1.17 g/cm3) = 1170 gm and there are 1000 gm in 1 kg, so we want enough liters to have a mass of 3.75 kg x 1000 gm/kg = 3750 gm Hence, # of liters = desired mass / # of gm per liter = 3750 gm / 1170 gm/liter = 3.2051282 liters</span>
