The weight of a 94 lb. sack of cement is incidental - the bag is packaged in that size in order to hold one cubic foot of cement, and 94 pounds is simply what one cubic foot of dry cement powder weighs.
Mix design for concrete was originally performed by volume and not by weight. Mix designers were initially concerned about variations in density and thought volume would deliver the most consistent results. As time progressed, they found that mix design were not adversly affected when designed by weight, (which was also much simpler), and therefore became used industry wide. Because 94lbs of cement is, as noted above, what 1 cubic foot of cement weighs, the 94 lb sack was a backhanded way for the mix designers to check the weight calculations easily with known volumes.

A U.S. bag (or sack) of cement contains 94 lbs. Note this is for cement not premixed concrete where you just add water. The origin of 94 lbs/sack for cement comes from 1 cubic foot of loosly bagged cement weighs approximately 94 lbs; they were originally (and perhaps still) measured out by volume, but for weight calculations, the weight of 94 lbs became standardized.
It wieghs about 94 pounds.
One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8 bags total. Some will be left over

If a person's mass is 94 kg, then the person weighs 207.2 pounds on earth, 33.8 pounds on the moon, and 78.7 pounds on Mars. The 94 kg of mass doesn't change, no matter where he is.
