Answer:
The number of mole is 0.04167mole
Explanation:
To convert gram to mole, we need to calculate the molecular weight of the compound
C6H12O6
C - 12
H - 1
O - 16
Molecular weight = 6 * 12 + 1 *12 + 6 * 16
= 72 + 12 + 96
= 180g/mol
To covert gram to mole
Therefore,
= 7.50g/ 180g/mol
= 0.04167 mole of glucose
Answer:
Most igneous, metamorphic, and sedimentary rocks contain rubidium (Rb) and strontium (Sr) in detectable amounts. However, the concentrations of these elements are almost always less than 1 percent, and they are therefore rarely determined in routine chemical analyses. Neither rubidium nor strontium is a major constituent in the common rock-forming silicate minerals, although strontium does form a carbonate (strontianite) and a sulfate (celestite) which are found in some hydrothermal deposits and certain sedimentary rocks, particularly carbonates.

Good luck!
Answer:
0.1
Explanation:
The retention factor is the ratio of distance traveled by sample to distance traveled by solvent. Its values range between 0-1. Zero means that the solvent is too nonpolar and its polarity must be reduced. An Rf of 1 means that the solvent is too polar and its polarity must be decreased. Two substances must differ in Rf at least by 0.1 to be effectively separated by chromatography.
The equilibrium state of a gas when it can hold all the molecules of water vapor is known as saturation.
<h3>Which three equilibrium conditions apply?</h3>
A solid substance subjected to three forces with divergent lines of action is in equilibrium if all three of the following three circumstances hold true:
- Coplanar action lines are present (in the same plane)
- The paths of action have come together (they cross at the same point)
- These forces add up to a vector with a total of zero.
<h3>What are equilibrium's first and second conditions?</h3>
An object must satisfy two requirements of equilibrium in order to maintain static equilibrium.
- First, there must be no net force acting on the item.
- Second, there must be no net torque pulling on the object.
