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
Answer
given,
mass of the solid door = 22 Kg
dimension of door = 220 cm x 91 cm
moment of inertia about the hinge
r is the distance from the one edge which is equal to 91 cm or 0.91 m
Moment of inertia about center for rectangular gate is equal to
moment of inertia for rotation about a vertical axis inside the door, 15 cm from one edge

Explanation:
circular motion means the object will follow a circular trajectory.
Answer:
The pressure difference is <em>.</em>
Explanation:
To calculate the pressure difference, we use the fluid-kinetic equation:
<em>Δp = (8μLQ)/(πR⁴)</em>
Step 1: Convert the units of the given terms to SI units:
Diameter = 0.56 cm X ( =
∴ Radius, R =
Length, L = 22 cm X ( = 0.22 m
Volumetric flow rate, Q = ÷ 2.0 minutes =
X X =
Step 2: Input the terms into the fluid-kinetic equation:
<em>Δp = (8 X 0.60 X 0.22 X 3.67) / (3.142 X ()</em>
<em>Δp = 20067.43 Pa = .</em>
N.B: The pressure difference is lower than the atmospheric pressure (101300 Pa), which means you can drink the milkshake through the straw.
