Answer:
0.0076kg
Explanation:
To get the mass, we use the relation among density, mass and volume.
Mass = density * volume
Here mass? , density = 0.779g/ml , volume = 9.76ml
Mass = 9.76 * 0.779 = 7.60g
Answer is wanted in kg so we divide by 1000. This is 7.60/1000 = 0.0076kg
Answer:
Characteristic of a substance that Cannot be observed without altering the identity of the substance.
Explanation:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points.
A human has 46 chromosomes which is 23 PAIRS
Answer:
Forumula
XOH + HY = XY + H2O
Explanation:
Salt formed from: Salt Solution
Strong acid + Strong base Neutral
Strong acid + Weak base Acidic
Weak acid + Strong base Basic
Neutral solution example
NaCl = Sodium chloride
HCl = H+ and Cl-
NaOH = Na+ and OH-
OH- = Strong Base
H+ = Strong Acid
Sodium chloride, formed from neutralization of HCl by NaOH.
NaOH + HCl = NaCl + H2O
NaCl in water is not acidic or basic, since it's ions cannot hydrolyze.
So formula would be XOH + YH = XY + H2O
The total mass is the sum of the masses.
It is
5543 + 23.45 + 697.4 mg = 6263.85 mg
Answer: 6263.85 mg
