Answer: how much mass is in a certain amount of space
Explanation: density is g/mL; therefore it’s the mass (g) in a certain amount of space (mL)
Post the question so we can help
The difference between natural dye and synthetic dyes is largely that synthetic dyes are chemically manufactured whereas natural dyes are purely developed from nature.
Answer:
16.7 g of glucose
Explanation:
Convert grams of H₂O to moles. <em>0.555 mol</em>
We can use the chemical equation to determine the theoretical yield. Based on the equation, for every 6 moles of H₂O, 1 mole of glucose is produced. The ratio of glucose moles to H₂O moles is 1/6.
Multiply the moles of H₂O by the ratio to find moles of glucose. <em>0.0925 mol</em>
Convert moles of glucose to grams. <em>16.7 g</em>
Answer:
26 g left undisolved which gives you the amount that would crystallize
Explanation:
Step 1: Data given
A solid mixture consists of 44.2g of KNO3 (potassium nitrate) and 7.8g of K2SO4 (potassium sulfate).
The mixture is added to 130. g of water
KNO3 has a solubility of 14 g solute/ 100 g water
Step 2: Calculate mass of KNO3 in 130 grams of water
X g of KNO3/ 130 g water= 14 g of KNO3/ 100 g water
X = 14*1300/100 = 18.2
X= 18.2 g (this is the amount of solute that dissolves at 0 degrees C in 130 g water)
Step 3: Calculate amount KNO3 that will crystallize
Of the 44.2g of KNO3 in 130 g of water at 0 degrees celsiusonly 18.2 can dissolve, this means:
44.2g - 18.2g = 26 g left undisolved which gives you the amount that would crystallize
