Density:
The density of a substance is equal to the ratio of its mass and volume. In general we can say the density of a substance is mass per unit volume.
Density = mass in g / volume in cubic cm or ml
Given that
Density = 8.92 g/ ml
Mass = 40.0 g
Therefore,
Volume = mass/ density
= 40.0 g/ 8.92 g/ ml
= 4.48 ml
Thus the correct answer is 4.48 ml
Answer:
Mn(NO3)3 Molar mass = (54.93) + (3 x 14) + (9 x 16) = 240.93g/mol
Total number of Oxygen atoms in formula = 9
Total mass of oxygen atoms theoretically in the formula = 9x16 = 144g/mol
Oxygen's percentage composition:
(144/240.93) x 100 = 59.7% of the compound is oxygen
Answer: Although the rocks of the produced by similar processes but their chemical composition may vary dependent upon the type of mineral present in these rocks so the color of the rock also varies depending upon the mineral composition.
Explanation:
The rocks are made by basic steps like disintegration of parent rock material, erosion, crystallization, metamorphism, and sedimentation. These basic steps are common in same kind of rocks but their color may vary because of the mineral composition in them for example, Rhyolite is of light colored because of the presence of quartz mineral present in it.
I believe it occurs along the plates edge.
