Asample of gas contains 0.1900 mol of h2(g) and 9.500×10-2 mol of o2(g) and occupies a volume of 10.1 l. the following reaction takes place: 2h2(g) o2(g)2h2o(g) calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant. l

it would be a gas formation

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
