Answer:
m = 0.0035 m.
Explanation:
Hello there!
In this case, since the formula for the computation of the molality is:
We can first compute the moles of solute, K3PO4 by using its molar mass:
Next, since the volume of water is 40.0 mL and its density is 1.00 g/mL we infer we have the same grams (40.0 g). Thus, we obtain the following molality by making sure we use the mass of water in kilograms (0.04000kg):
In molal units (m=mol/kg).
Best regards!
That a particular concept- the Alcubierre Warp Drive- might actually be feasible.... the major hurdles and opportunities presented by warp mechanics research
S because As is not a non-metal
The spring constant determines how far the spring will stretch for a given applied force: <span>F=kx→k=<span>Fx</span></span><span>. If we place the same mass on the two springs, which means we have placed the same force on them, the one that stretches </span>least<span> has the largest spring constant.
Hope this helps!
