Seawater consists of many important elements in the form of salts dissolved in the water. At 25°C the mass percentage of salts in seawater will total 3.5% m/m. The density of seawater at this temperature and salt percentage is 1.024 kg/L. Study the chart and answer the questions below:   1. The chart assumes 1000.0 g of seawater. What volume, Vsoln (L), does this correspond to at 25 °C? 2. The diagram claims that chloride ions make up 55% m/m of all salt ions. Confirm this number.   if possible, I would like handwritten answers with calculations. Thanks :)

Seawater consists of many important elements in the form of salts dissolved in the water. At 25°C the mass percentage of salts in seawater will total 3.5% m/m. The density of seawater at this temperature and salt percentage is 1.024 kg/L. Study the chart and answer the questions below:
 
1. The chart assumes 1000.0 g of seawater. What volume, Vsoln (L), does this correspond to at 25 °C?
2. The diagram claims that chloride ions make up 55% m/m of all salt ions. Confirm this number.

c) Sjøvann består av mange viktige grunnstoff i form av salter som er oppløst i vannet. Ved 25 °C
vil masseprosenten av salter i sjøvann totalt utgjøre 3.5 % m/m. Tettheten av sjøvann ved denne
temperaturen og saltprosent er 1.024 kg/L. Studer diagrammet og svar på spørsmålene under:

Quantes in relation to 1 kg or 1 litre of sea water.
1. Diagrammet antar 1000.0 g sjøvann. Hvilket volum, Vsoln (L), tilsvarer dette ved 25 °C?
2. Diagrammet påstår at kloridioner utgjør 55 % m/m av alle saltioner. Bekreft dette tallet.
3. Diagrammet påstår at natriumioner utgjør 30.6 % m/m av alle saltioner. Beregn molar
konsentrasjon av natriumioner i sjøvann fra disse data. Ta hensyn til korrekt volum, Vsoln-
