Answer:
40g/mol
Explanation:
The molar mass of a compound is the mass in grams of one mole of the substance.
To find the molar mass of NaOH;
a. Atomic mass of Na = 23g
O = 16g
H = 1g
b. So, the NaOH will have a molar mass of:
23g + 16g + 1g = 40g/mol
The molar mass of NaOH is 40g/mol
1. Using Strong Permanent. 2. increasing the current. 3. Decreasing the space between Magnets
Explanation:
Brainiest
Answer:
98 N
Explanation:
Given that The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). Of an object’s mass is m=10. kg,
The parameters to be considered are
Mass m = 10 kg
Acceleration due to gravity = 9.8m/s^2
Weight W = mg
substitute mass m and acceleration due to gravity g into the formula above.
Weight = 10 × 9.8
Weight = 98 N
Therefore, the weight of the body or object is 98 N
Answer:
d. All three statements are true.
Explanation:
In the metals the electrons are the charge carriers and they are the only mobile charges causing the flow of current when subjected to potential difference.
The electrons being negatively lead to the flow of current in opposite direction. The direction of the current is opposite to the direction of the negative charges.
