A I’m sure of it because it only makes since one would think ✊
Hey thee fella!
Based on my broad information, the systems that help human to support there-selves would actually be the ( skeletal systems).
Hey there!
Molar mass CuSO4 = <span>159.609 g/mol
</span><span>Note that the molarity is in the enunciation of the issue, then the problem asks the mass of the solute :
Volume in liters of solution:
150 mL / 1000 => 0.15 L
</span><span>Calculation of quantity in Moles of the solute :
</span>
1 L ----------------- 0.300 M
0.15 L ------------ ( moles )
Moles CuSO4 = 0.15 * 0.300 / 1
Moles CuSO4 = 0.045 moles
Therefore :
1 mole CuSO4 --------------------- 159.609 g
0.045 moles CuSO4-------------- mass
mass = 0.045 * 159.609 / 1
mass = 7.182405 g of CuSO4
The number of complete waves, or complete cycles, per unit of time is called the frequency. Because every complete wave has one crest and one trough, you can think of the frequency as the number of crests or troughs produced per unit time. The unit used to measure wave frequency is called the hertz (Hz)
Answer:
is this true and false? then its true
