Explanation:
The history of the metric system began in the Age of Enlightenment with notions of length and weighttaken from natural ones, and decimal multiples and fractions of them. The system became the standard of France and Europe in half a century. Other dimensions with unity ratios[Note 1] were added, and it went on to be adopted by the world.
Answer:
chromium:oxygen=1:2
Explanation:
total mass=2.16g
mass of chromium=1.34g
mass of oxygen=2.16g-1.34g=0.82g
chromium oxygen
mass:1.34g 0.82
RAM:52 16
divide the mass with the RAM
0.02577 0.05125
divide by smallest number to find ratio
1 2
ratio of chromium to oxygen=1:2
Answer:Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.
