Answer:
it depends on what kind of cheese you are getting
These are known to be saturated.
The definition of a saturated fatty acid is that the carbon chain coming off of the acid group contains only single bonds. An unsaturated fatty acid contains at least one double bond in the carbon chain coming off of the acid group. Saturated fats are usually fats (solid at room temperature) while unsaturated fats can be oils (liquid at room temperature) this is because the single bonds in the saturated fats give the molecule a shape that can stack on another saturated fat molecule more easily which makes the melting points higher. The double bonds (usually referring to cis double bonds since trans double bonds are in trans fats) in unsaturated fats give the molecule a shape that cannot stack on another unsaturated fat molecule easily which makes the melting point lower.
I hope this helps. Please let me know if anything is unclear or if you want further explanation.
<span>moles water = 850.0 g / 18.02 g/mol=47.2
moles Mg2+ = 0.400
moles Cl- = 2 x 0.400 = 0.800
moles ions = 0.400 + 0.800= 1.2
mole fraction ions = 1.2 / 1.2 + 47.2 =0.0248</span>
Answer:
a) Molarity = 0.199M
b) 21.6L of solution
c) 0.199 moles of sucrose in 1L
Explanation:
a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):
<em>Moles sucrose -Molar mass: 342,3g/mol-:</em>
225.0g * (1mol / 342,2965g) = 0.6573 moles
Molarity = 0.6573 moles / 3.30L
<h3>Molarity = 0.199M</h3><h3 />
b) 0.199M means 0.199 moles in 1L. 4.30 moles are in:
4.30 mol * (1L / 0.199mol) = 21.6L of solution
c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M
